[v4] rust: Add Lock::from_raw() and expose Guard::new()

[PATCH v4 0/2] rust: Add Lock::from_raw() and expose Guard::new()

Posted by Lyude Paul 1 year, 2 months ago

This is the third version of a small patch series to introduce
interfaces for working with locks that we've acquired from raw C
pointers, something that is quite useful for bindings like the rust
bindings - where there's a number of interfaces protected by BFLs, or
which require the implementation of callbacks that are known to occur
under lock.

  rust: sync: Add Lock::from_raw() for Lock<(), B>
  rust: sync: Make Guard::new() public
